Life-saving appliances are those appliances that protect human life at sea. The devices are documented as part of the International Convention for the Safety of Life at Sea, or SOLAS Convention. [1]
In the SOLAS Convention and other maritime related standards, the safety of human life is paramount. Ships and other watercraft carry life saving appliances including lifeboats, lifebuoys, life-jackets, life raft and many others. Passengers and crew are informed of their availability in case of emergency. Life-saving appliances are mandatory as per chapter 3 of the SOLAS Convention. The International Life-Saving Appliance (LSA) Code [2] gives specific technical requirements for the manufacture, maintenance and record keeping of life-saving appliances. The number and type of life-saving appliances differ from vessel to vessel, and the code gives a minimum requirement to comply in order to make a ship seaworthy.
The International Maritime Organization is a specialised agency of the United Nations responsible for regulating shipping. The IMO was established following agreement at a UN conference held in Geneva in 1948 and the IMO came into existence ten years later, meeting for the first time in 17 March 1958. Headquartered in London, United Kingdom, IMO currently has 175 Member States and three Associate Members.
A flare, also sometimes called a fusée, fusee, or bengala, bengalo in several European countries, is a type of pyrotechnic that produces a bright light or intense heat without an explosion. Flares are used for distress signaling, illumination, or defensive countermeasures in civilian and military applications. Flares may be ground pyrotechnics, projectile pyrotechnics, or parachute-suspended to provide maximum illumination time over a large area. Projectile pyrotechnics may be dropped from aircraft, fired from rocket or artillery, or deployed by flare guns or handheld percussive tubes.
SOS is a Morse code distress signal, used internationally, originally established for maritime use. In formal notation SOS is written with an overscore line, to indicate that the Morse code equivalents for the individual letters of "SOS" are transmitted as an unbroken sequence of three dots / three dashes / three dots, with no spaces between the letters. In International Morse Code three dots form the letter "S" and three dashes make the letter "O", so "S O S" became a common way to remember the order of the dots and dashes.
A distress signal, also known as a distress call, is an internationally recognized means for obtaining help. Distress signals are communicated by transmitting radio signals, displaying a visually observable item or illumination, or making a sound audible from a distance.
The Global Maritime Distress and Safety System (GMDSS) is a worldwide system for automated emergency signal communication for ships at sea developed by the United Nations' International Maritime Organization (IMO) as part of the SOLAS Convention.
The International Ship and Port Facility Security (ISPS) Code is an amendment to the Safety of Life at Sea (SOLAS) Convention (1974/1988) on Maritime security including minimum security arrangements for ships, ports and government agencies. Having come into force in 2004, it prescribes responsibilities to governments, shipping companies, shipboard personnel, and port/facility personnel to "detect security threats and take preventive measures against security incidents affecting ships or port facilities used in international trade."
The International Convention for the Safety of Life at Sea (SOLAS) is an international maritime treaty that sets minimum safety standards in the construction, equipment and operation of merchant ships. The International Maritime Organization convention requires signatory flag states to ensure that ships flagged by them comply with at least these standards.
A personal flotation device is a flotation device in the form of a vest or suit that is worn by a user to prevent the wearer from drowning in a body of water. The device will keep the wearer afloat with their head and mouth above the surface – they do not have to swim or tread water in order to stay afloat and can even be unconscious.
A chief mate (C/M) or chief officer, usually also synonymous with the first mate or first officer, is a licensed mariner and head of the deck department of a merchant ship. The chief mate is customarily a watchstander and is in charge of the ship's cargo and deck crew. The actual title used will vary by ship's employment, by type of ship, by nationality, and by trade: for instance, chief mate is not usually used in the Commonwealth, although chief officer and first mate are; on passenger ships, the first officer may be a separate position from that of the chief officer that is junior to the latter.
A second mate or second officer (2/O) is a licensed member of the deck department of a merchant ship holding a Second Mates Certificate of Competency, which is issued by the administration. The second mate is the third in command and a watchkeeping officer, customarily the ship's navigator. Other duties vary, but the second mate is often the medical officer and in charge of maintaining distress signaling equipment. On oil tankers, the second mate usually assists the chief mate with the cargo operations.
A third mate (3/M) or third officer is a licensed member of the deck department of a merchant ship. The third mate is a watchstander and customarily the ship's safety officer and fourth-in-command. The position is junior to a second mate. Other duties vary depending on the type of ship, its crewing, and other factors.
The International Register of Shipping or IS was established in 1993, and is an independent classification society which provides classification, certification, verification and advisory services. The International Register of Shipping also offers consulting services well suited for the shipping and offshore industry.
The general emergency signal is a signal used on board ships in times of emergency.
A marine evacuation system (MES) is a lifesaving device found on many modern passenger ships or oil rigs consisting of an inflatable slide or escape chute where a passenger can evacuate straight into waiting life rafts. Developed in 1979 by RFD, a New Zealand–based company that distributes safety equipment; MES is replacing traditional davit-launched life rafts used on ships.
The IMO number of the International Maritime Organization is a generic term covering two distinct meanings. The IMO ship identification number is a unique ship identifier; the IMO company and registered owner identification number is used to identify uniquely each company and/or registered owner managing ships of at least 100 gross tons (gt). The schemes are managed in parallel, but IMO company/owner numbers may also be obtained by managers of vessels not having IMO ship numbers. IMO numbers were introduced to improve maritime safety and reduce fraud and pollution, under the International Convention for the Safety of Life at Sea (SOLAS).
A lifeboat or liferaft is a small, rigid or inflatable boat carried for emergency evacuation in the event of a disaster aboard a ship. Lifeboat drills are required by law on larger commercial ships. Rafts (liferafts) are also used. In the military, a lifeboat may double as a whaleboat, dinghy, or gig. The ship's tenders of cruise ships often double as lifeboats. Recreational sailors usually carry inflatable liferafts, though a few prefer small proactive lifeboats that are harder to sink and can be sailed to safety.
The sinking of the Titanic resulted in the following changes in maritime policy:
Vessel safety surveys are inspections of the structure and equipment of a vessel to assess the condition of the surveyed items and check that they comply with legal or classification society requirements for insurance and registration. They may occur at any time when there is reason to suspect that the condition has changed significantly since the previous survey, and the first survey is generally during construction or before first registration. The criteria for acceptance are defined by the licensing or registration authority for a variety of equipment vital to the safe operation of the vessel, such as safety equipment, lifting equipment, hull structure, static stability, ground tackle, propulsion machinery, auxiliary machinery, etc. The SOLAS Convention, specifies safety equipment for commercial vessels operating internationally.
The FSS Code or International Code for Fire Safety Systems is a set of international treaties organised by the International Maritime Organization (IMO) under the SOLAS Convention that are designed to reduce the risk of fire, and aid in emergency response aboard ships. Some of the components of the code were constructed after some high-profile passenger ship disasters over the last century.
A Thermal Protective Aid (TPA) is an aluminized polyethylene suit with heat sealed seams that protects from the elements and prevents hypothermia.
